Abstract
A two-optic accommodative lens system. The first lens (12) has a negative power and is located posteriorly within the capsular bag and laying against the posterior capsule. The periphery of the first optic (12) contains a pair of generally T-shaped haptics (16) having a generally rectangular slot (18) within the top portion of the "T". The second optic (14) is located anteriorly to the first optic (12) outside of the capsular bag and is of a positive power. The peripheral edge of the second optic contains a pair of encircling haptics (24) having a notched tab (28) sized and shaped to fit within the slots (18) in the haptics (16) on the first optic (12) to lock the second optic (14) onto the first optic (12). Hinge structures (26) on the encircling haptics (24) allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle.
Claims (5)
1. An intraocular lens, comprising:
a) a first optic having a haptic with a slot;
b) a second optic having at least one haptic, the haptic being connected to the second optic by a hinge region; and c) a notched tab located on the haptic of the second optic, the notched tab sized and shaped to penetrate and be received in the slot and thereby movably attach the second optic to the first optic.
a) a first optic having a haptic with a slot;
b) a second optic having at least one haptic, the haptic being connected to the second optic by a hinge region; and c) a notched tab located on the haptic of the second optic, the notched tab sized and shaped to penetrate and be received in the slot and thereby movably attach the second optic to the first optic.
2. The lens of claim 1 wherein the hinge region allows the second optic to vault away from the first optic in reaction to compression of the first optic.
3. The lens of claim 1 wherein the first optic and the second optic comprise a soft acrylic material.
4. The lens of claim 1 wherein the second optic comprises a hydrogel material.
5. The lens of claim 1 wherein the second optic comprises a silicone material.
